My concerns over iOS 7 preparations lingered during WWDC, but once
I returned home I realized my mistake. In fact, there is already
an app in the App Store from which I can draw inspiration for this
new style. An app that adopts the look and feel of iOS 7 by
elevating the content over the chrome. An app that uses color and
animation in the style of iOS 7 to clarify content. I realized
that, for all intents and purposes, Vesper is the first iOS 7 app
in the App Store. Despite being an iOS 6 app, Vesper adopts the
major idioms of iOS 7 and serves as a great example of how
developers can adopt those same idioms and still retain an
individual identity for their app.

This made my day, but allow me to put my humble hat on for a moment, and praise two apps that foreshadowed iOS 7 long before Vesper: Letterpress and Twitterrific 5. I’ve been a TweetBot man for quite a while, but on my iOS 7 testing device, I find Twitterrific is the only Twitter client that feels right at home.
